Abstract
A computer simulation model which represents the detailed working of a specific bus service is reported. The service modelled has a cross town route with a medium headway (10 mins) and the round-trip time is approximately 1½ hours. The successful validation of the model against the observed behaviour of the real bus service is described, and the model is then used to estimate the likely effect of applying several control strategies formulated for use in a situation where the exact positions of all buses in service are known.
